Selling and buying online goods and servcies is becoming more pouplar than other conventional methods of doing business. Sellers list and sell their products through their own private websites or through online marketplaces. And byers buy goods of their choice from these sellers through these markeplaces. There are many famous online marketplaces of all sizes and types. For a novice seller, selling through an online marketplace seems to be a simple and time saving business proposition. But in reality, while all the real hardwork is carried out by the seller, it is not a cheaper way of selling products through major marketplaces. In many cases on average an online marketplace takes 40% to 60% of revenue of a seller from its sales in the form of selling fees and commissions. For this reason there is a need that new online challenger marketplaces should emerge to challenge the business practices and policies of current major online marketplaces. What is your view on this?
Sounds like you have an essay to write. Wish and AliExpress have a stranglehold on the "cheap and cheerful" market. You're probably right about the commission problem. We see it with UberEats, with sites like hotels.com/agora etc. It's a lot of work running a site like that and I imagine they earn those commissions.
The Facebook marketplace is a fantastic location to sell any goods and grow your company from a small starting point.
I think there should definitely be more marketplaces that would suit different businesses and requirements. Lately, marketplaces on social media have become very popular and many people are finding products and making purchases there, although there isn't some defined space for doing that, people are just selling through their profiles and groups.
Commissions are indeed the problematic side of trading. But the only alternative is your own website, and for this you need to be a recognizable brand.
